A simple way to obtain substantial savings:
The Galley Demand Controlled Ventilation system (GDCVs) system is making savings simple by reusing the existing equipment, but controlled differently. GDCVs consider the entire saving potential in both hood, canopies and galley with variable air volume (VAV) and variable cooling.
GDCVs can identify the load on the cooking device and the galley activity. Existing hood/canopy dampers will close when the cooking equipment is not in use, and the exhaust air reduced and the supply air reduced to keep a slight under pressure to surrounding areas.
Modification of the system from constant air volume and supply air control to room VAV, temperature, humidity control, to increase the well-being and saving.
The first step is a survey and saving analyze.
Next step is to install needed equipment, which is Hood/Canopy IR sensors – current meters – solenoid valve signal, Damper aux. relay, room temperature, humidity and differential pressure sensors, the new interface control cabinet and serial cable to existing HVAC Control system and modify the software. VFD’s for fans and a cooling valve if not already installed.
Last step is to test and commissioning the system to feel the improved comfort and save at the same time.
